Thread: More evidence that the world has gone mad!
03/12/2019 22:23:06

Ford sold a car in Brazil called a Pinto. Unfortunately it is Portuguese slang for little dick!

Thread: Long bed lathes affected by the tide

When they built the Shard in London, they had to take a building down first. They were worried about heave when the building was removed as the ground would rise due to the weight being removed.

Thread: Brass Tarnishing
28/11/2019 11:13:17

I tried renaissance wax several times and it's crap. Briwax was the best wax I found to stop tarnishing.

Thread: Aluminium welding
15/11/2019 20:15:47

I have found most of the welding rods are full of silicon and other crap. I normally make my on rods out of the same material as I welding or I just cut up ali sheet into strips.

If you are gas welding ali you need to use American flux as the EU flux has changed and is next to useless.

Thread: Moore and Wright Micrometer

I would suspect it's a press fit.

Thread: Cast iron welding electrodes
29/10/2019 12:26:07

When ever I weld cast iron, I heat up the weld area to a cherry red with a pepper pot burner, then weld it but use a circular action to pool the rod with the base metal. Then reheat the site to cherry red and pack in dry sand. The alternative is to metal stitch the crack cold.

Does this help? **LINK**

Yes it was part of the question in the post!

I think Warco do one.

I don't think that was the original question smiley

Thread: Better work
25/10/2019 22:35:11

I used to run a blacksmith business and I used to have the opposite problem. I would get a commission to make a pair of gates, when I finished them i was never happy with them. My customers were always extremely pleased with my work. When I saw my later on I used to see them I used then appreciate how good they were!

I was told engineers rarely make good clock makers or blacksmiths!frown

Thread: Reaming a large diameter by hand
25/10/2019 09:25:22

I would set it all up in mill so as everything is straight and rigid.

Thread: Stripped thread / Pultra P type
25/10/2019 09:23:50

If it doesn't take a high load. You could clean the brass nut and tin it, the drill a hole in one side, fit the cross shaft and pour white metal into the hole.

This was a quite common method for making steering box female worms.

Conrods look an odd design.

Thread: Bending stainless rod

Just the sort of jig used for production work in a forge!

Posted by Paul Ainsworth on 20/10/2019 12:38:30:

Revised jig, I'll see how this goes.

Make a dummy split collet, clamp it solid in a vice and use a oxy propane pepper pot burner to heat it up and the bend to suit. Afterwards pack in dry sand to allow it to cool slowly.

Never cool any steel in water as this could cause chemical changes or hardening. Even mild steel will change it's structure. Unless the steel is "new" you don't know what else is in the steel!

Modern cars now contain all sorts of exotic steels and when the cars are scrapped most of them go through a frag machine which grinds up the steel ready for recycling. This material contains boron, vanadium, chrome, nickel and high carbon steels. This all goes into the pot for mild steel.

Unless you can find a supplier who supplies new steel you really don't know what your buying.

If I need a specific grade of steel I ask for a Certificate of Conformity and the steel is normally more expensive.

Thread: Limiting pressure to a gauge
20/10/2019 11:33:53

This is a 1910 engine with open oil galleries drip feeding the main bearings and dippers feeding the big ends. The oil is pumped down the exhaust cam, which has oil ports drilled to line up with the galleries as the came rotates. There is no pressure relief valve and it is quite common on early engines not to have one. These engines have large oil pumps and work by supplying a large volumes of oil, rather than low volumes and high pressure.

Thank you all for you advise. I will do some experiments with restrictors or pegging the gauge. The engine is a Dennis Brothers engine and is one of four experimental engines they made for testing a new design, so information is non existing!

I spoke to John Dennis and he checked his records and confirmed that all four engines were scrapped! We think someone sold them out the back door instead of scrapping them!

Posted by Hopper on 18/10/2019 09:15:41:

They wouldn't have had relief valves and restrictors back in 1910. Just do what the original manufacturer did. Must be information available somewhere. Or others on the net with same kind of engine. Probably just let the gauge peg when cold and carried on regardless. Lot of that old stuff was pretty crude yet still functioned.

Most vintage Harley engines are much the same. If you fit an oil pressure gauge it pegs it on cold start up then settles down to 10psi running pressure. The gauges seem to survive.

Thread: Anyone know about buying freehold to a house in the north
16/10/2019 22:18:28

If they are going to sell it on the open market there must room for profit. If you decide to sell your property the landlord can charge you to reassign the lease to the purchaser.

I would read the lease very carefully.

Posted by Ian Parkin on 16/10/2019 20:53:08:


its the church actually

They say if i dont buy within a month they will assume i dont want to and then put it on the open market

next question...... Why would some company want to buy it ?

Surely not for the privilidge of invoicing me for £6 every year

This cant go up for 800~+ years

Theres no covenents saying I have to ask to do anything to the said house

Its in a conservation area so not much scope fro extending

Thread: Limiting pressure to a gauge
16/10/2019 21:39:22

I am rebuilding a 1910 5 litre petrol engine. On start up the oil pressure peaks at 70 psi but the running pressure is 15 psi. I need to limit the pressure reaching the gauge on start up as the gauge only reads to 30 psi?

Buy it or someone else might buy it and impose charges on you!
